A perfectly rigid body has value of Young's modulus -
Option A: Zero
Option B: Infinite
Option C: One
Option D: None of the above

Answer is Infinite
Young modulus=stress/strain
Since the body is perfectly rigid, it will not experience any change in length.
therefore strain=0
Y.M.=stress/0=INFINITY

in other words, Y.M. for perfectly rigid body is "NOT DEFINED!"
